Floor construction



P 1934. K. P. BILLNER FLOOR CONSTRUCTION Fi led Feb. 25, 1951 INVENTOR M/'i 5% BY Q ATTORNEY Patented Sept. 18, 1934 V UNITED STATES PATENTOFFICE FLOOR CONSTRUCTION Karl P. Billner, New York, N. Y., assignor toThe Aerocrete Corporation of America, New York, N. Y., a corporation ofDelaware My invention relates to new and useful improvements in floorconstruction and my object is to provide for a floor construction ofsimple form, of light Weight, high structural strength and which can beset up quickly and economically.

In order that the invention may be better understood attention isdirected to the accompanying drawing, forming a part of thisspecification and in which Figure 1 is a sectional view of my improvedfloor construction in its preferred form taken on the line 1-1 of Figure2, and I Figure 2 a section of the same taken on the line 22 of Figure1.

My improved floor construction involves the use of longitudinal elements1-1 and transverse elements 22. Longitudinal elements 1-l may extendeither longitudinally or transversely of the building in which the flooris to be constructed and are supported by the usual side walls or bysuitable pillars or piers. Preferably the elements l--1 are I beamsarranged a substantial distance apart, say from twelve to thirty feet.

The transverse members 2-2 are also preferably I beams as shown placedcloser together and extending at right angles to elements 1--1. Aconvenient spacing of the elements 22 may be from two to eight feetapart depending upon their load carrying capacity. The elements 22 restupon angle irons 3-3 which are slotted at 4, straddling a bolt 5 bywhich angles 33 may be firmly secured to the web 6 of the adjacent Ibeam 1. The members 22 are secured to the angles 3 by rivets 7 or in anyother suitable way.

The I beams 22 are cut away at 8 as shown so as to clear the upperflange of the I-beams 1 and the two adjacent members 22 are connectedtogether byv a plate 9 and rivets 10. The

49 plates 9 preferably rest upon the upper flange of the I beam 1. Theends of the members 22 preferably abut against the web 6 of the I beam 1or they may be slightly separated from this Web as shown.

A filling 11 of a suitable light concrete is now cast around the steelstructure thus formed by means of suitable molds (not shown) for thepurpose. The'concrete projects at 12 to surround the dependent part ofthe I beams 1-1 to thus give a finished appearance to the ceiling below.The light concrete 11 may be of any suitable type, the preferred formbeing a porous concrete having numerous cells or pores therein andconstructed in accordance with the patent to Aylsworth and Dyer, No.1,087,098.

Having now described my invention what I claim as new therein and desireto secure by Letters Patent is as follows:

1. A floor construction comprising heavy Ion-- gitudinal I beams spacedrelatively far apart, brackets secured to said beams, light transverseI-beams spaced relatively close together and carried by and secured tosaid brackets with their upper faces substantially in line with theupper faces of the longitudinal beams, a plate connecting each pair oftransverse beams and a filling of light weight concrete surrounding ands0 imbedding all of said beams so as to give a finished appearance tothe ceiling below.

2. A floor construction comprising heavy longitudinal members in theform of I-beams spaced relatively far apart, brackets secured to theWebs of the longitudinal members, light transverse members supported byand secured to said brackets and being cut away to accommodate the upperflange of the adjacent I beam whereby the upper faces of said transversemembers will be in substantially the plane of the upper faces of saidlongitudinal members and a filling of light weight concrete surroundingand embedding said longitudinal and transverse members so as to give thefinished appearance of a beamed ceiling below.
